Flame Relay

RF-FR-01 is a multifunctional flame relay that can be used with BFD1-U-I series flame detectors or flame rods. Its function is to converts from a flame detector open collector signal in a binary signal ON/OFF for access to systems such as PLC and DCS or indicator lights.

RF-FR-01 has two LEDs indicator of flame signal and power supply.

Compared to common products on the market, the unique feature is the integrated flame signal out response time selection function, which can be selected in 1 second or 3 seconds.

 Parameter

• Power supply: 230VAC，50/60HZ
• Fused power rating: 100mA
• Suitable for flame detection: BFD1-U-I、flame rod
• Output signal: NO/NC、ON/OFF signal
• Contact rating: Max.250VAC,3A
• Installation: rail mounting

Explosion Proof Pressure Switch

The Rapidflame RFPS-EX series pressure switches are designed specifically for use in explosion-proof environments. The pressure switch adopts a diaphragm type and can be used for detecting gas pressure. The function of converting pressure signals into electrical signals can be achieved through the switch contacts. The pressure switch can be used alone or integrated into the gas control system.

Parameter

• Can be used for gas or air
